We report on a child with mild encephalopathy with reversible splenial lesion (MERS) associated with influenza infection and present a case series of neurological complications associated with influenza infections in children who presented to a tertiary children's hospital in Australia over a period of one year.

Intimal intussusception is an uncommon variation of aortic dissection, resulting from circumferential detachment and stripping of the intima in the setting of a Stanford type A dissection. The resultant tube of detached intima may prolapse either antegrade into the aortic lumen or retrograde into the left ventricular cavity. We classify these forms of dissection as antegrade and retrograde Stanford type A intimal intussusception. We present two cases with intimal intussusception and a review of the current literature. The majority of previous cases have been reported in the cardiology and cardiothoracic surgical literature, with few previous radiological reports.
